REGISTER.

SPECIFICATION forming part of Letters Patent No. 501,260, dated July 11, 1893.

Application filed July 25,1891.

.To w whom it may concern.-

Be it known that we, OLIVER F. SWIFT and WILLIAM WARWICK, of Buffalo, Erie county, State of New York, have jointlyinvented certain new and useful Improvements in Regisp ters; and We do hereby declare that the following description of our said invention, taken in connection with the accompanying sheet of drawings, forms a full, clear, and exact specification, which will enable others skilled in the art to which it appertains to make and use the same.

This invention has general reference to irnprovements in registers, and it consists, essentially, in the novel and peculiar combination of parts and details of construction, as hereinafter rst fully set forth and described and then pointed out in the claims.

In the drawings already mentioned, which serve to illustrate our said invention more fully, Figure 1 is a perspective view of our improved register. Fig. 2 is a sectional view in line a: x of Fig. 1, showing the wings closed. Fig. 3 is a similar view, showing the wings open.l Fig. 4. is a longitudinal ysectional elevation in line y y of Fig. 3.V

Like parts are designated by corresponding letters of reference in all the figures.

The object of this invention is the production of a register constructed entirely or partly of sheet metal, preferably sheet steel.

A is the frame of our sheet metal register. It is formed in two separate U shaped pieces A A, which pieces are riveted to lap or backing-plates B B', passing overthe adjacent ends of the frame pieces and provided withv inwardly-turned lugs b, having the usual apertures for the attachment of face-plates, (not shown,) by means of the usual screws. The lower edges of the frame are inwardly turned at d, to form a strengthening rib and a bearing for the wings O. These wings C have on their ends upturned lugs c c', those on one side, (c) being provided with a single perforation d, through which rivets d are passed to form pivots around which these wings may turn, while those on the opposite ends (c) are slightly enlarged and receive two perforations d ande respectively, the former receiving rivets d forming `pivots as described with reference to the lugs c, and

the latter toV receive rivets e', which removably connect these lugs c with a connecting rod E, so that by turning the center-wing by means of a lever F, attached thereto, all the 55 wings C will revolve around their pivots simultaneously to open and close the register,

as the case may be. In inserting these rivets l they are passed into their respective apertures from the back of the lap-plates B B,whereby 6o they are retained in position by the frame, without any further fastening, though they` may be upset in the usual manner on their heads, as shownin Fig. 4, if so desired.

In producing the casingA in two U shaped pieces we derive advantages which make it an object for us to construct them in the manner described, the principal one of which is a saving in material; but we do not wish to confine ourselves to this method of pro- 7o cedure exclusively, since'we may draw the entire frame in a suitable draw-press and `properly-constructed draw-dies in the form 'lar and suitable means, thereby producing registers of a very durable construction at a minimum of cost.

Usually cast iron frames for registers are made tapering to enable the patterns used in molding them to be drawn from the sand. This is an objection which reduces the effective area some twenty to twenty-five per centum, and may be avoided by our con- 9o struction which allows the sides of the frame to be made parallel or tapering as desired, or two sides'may be made parallel and the two other sidesconverging, the method of procedure being very flexible and capable of deviations with ease from the standard construction as well as sizes.

A register of a given size made from sheet metal weighs from fty to seventy-five per cent. less than one of corresponding size conroo structed from cast iron, the difference in weight alone leaving a good margin of profit over casting. These sheet-1netal registers are, furthermore, more durable; being almost indestructible and form a very desirable article of manufacture.

Another advantage is that, the metal being so much smoother than cast iron7 it requires less japan or paintto coat them, less space for packing and less bulk for transportation, all being items of considerable importance to a manufacturer of this class of goods.

Instead of securing the lever F to one of the wings, it may be fastened to, or formed in one piece with, the said connecting rod E, this deviation from the construction described poing a matter of choice with the manufacurer.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent of the United States- 1. As an improved article of manufacture, a sheet-metal register having its frame composed of two U shaped sections secured together by backing pieces having inwardlyprojecting, perforated lugs, one of which having the apertures for the pivots, and the other having two apertures one for the journaling pivots, and the other for the pivots of the connecting rod, as described.

2. In a register, the combination, with the frame consisting of two U shaped pieces of the backing pieces having inwardly-projecting perforated lugs, rivets in said backing pieces projecting therefrom and forming pivots for the wings, further rivets in said wings forming pivots for, and connecting the co'nnecting rod with, said wings and a lever secured to one of said wings, as and for the object stated.

3. As an improved article of manufacture, a sheet-meta1 register composed of two U shaped sections having an inwardly-projecting ledge at their lower ends, backing plates securing the adjacent ends of said frame and provided with inwardly-proj ectin g perforated lugs and with rivets forming pivots for the wings,the series of Wings having lugs on one end engaging the rivets of one of the backing plates and further wings at their other end engaging the rivets of the opposite backing plate, rivets in said last-named wings, a connecting rod engaging these rivets, and a lever for operating said wings, as and for the object stated.

In testimony that we claim the foregoing as our invention we have hereto set our hands in the presence of two subscribing witnesses.
